How do electromagnetic waves differ from mechanical waves?

• Mechanical waves have crests and troughs, but electromagnetic waves do not

• Mechanical waves need a medium through which to travel, but electromagnetic waves do not.

• Electromagnetic waves come in many types, but mechanical waves are all the same.

• Electromagnetic waves carry energy, while mechanical waves carry matter.

The chart below shows the range of wavelengths for different types of electromagnetic waves. Use the data in the chart to answer the question below.
